Filed: 1966-03-23
Abstract: 1,185,161. Extrusion; parison section control. H. V. SMITH. 31 May, 1967 [23 March, 1966], No. 12929/66. Heading B5A. The cross-sectional area of an extrudate is controlled by governing the pressure of material behind the die by control means responsive to displacement of a cam or templet and follower. These may co-operate to regulate a ram speed control device or by determining the rate of delivery of material to the die by a reciprocable screw. A programme may control the extrusion rate e.g. by controlling power operating means of the extruder. The extrudate may be a parison for blow-moulding e.g. of a bottle, being thickened at the point to be the junction of wall and base or the junction of wall and neck or both.

Title: Power recovery cathode ray beam deflection systems
IPC: H04N3/18
Filed: 1950-05-23
Abstract: 673,506. Television. RADIO CORPORATION OF AMERICA. May 23, 1950 [May 24, 1949], No. 12932/50. Class 40 (iii). [Also in Group XL (c)] In an electromagnetic scanning circuit of the type in which part of the scanning cycle is produced by current flow in a damping diode circuit and in which the H.T. supply voltage is boosted by the voltage developed across a storage capacitor, the deflecting coils are fed from the driver stage via an autotransformer of which at least a portion forms part of the anode cathode circuit of the driver valve. The deflection coils are connected directly in parallel with a second portion of the transformer, the storage capacity is connected in the anode-cathode circuit of the driver valve and the damping diode is connected across a series combination of the storage capacity and a third portion of the transformer. The Figure shows a television receiver in which a saw-tooth voltage 25 at line frequency produced in stage 24 is fed to a driver valve 34 to produce a saw-tooth current flow in coils 64; part of the scanning cycle when valve 34 is cut-off being produced by current flow in damping diode 74. During this portion of the cycle, capacitors 56, 62 are charged in a direction to supplement the H.T. voltage from source 60 applied to valve 34 during its conductive period. The linearity of the sawtooth current may be controlled by variation of inductor 58 and the amplitude of the scan by variation of inductor 104 in shunt with a portion of the autotransformer winding. The heater current for the damping diode 74 is supplied from a separate heater transformer 80 the effect of stray capacity 82 which would otherwise be effectively in parallel with the anode-cathode path of the diode is reduced by connecting one side of the heater and the cathode to spaced points d and b respectively on the autotransformer. E.H.T. supply for the final anode of cathode-ray tube 16 is derived by rectification in valve 84 of the line flyback voltage produced across the autotransformer winding and subsequent filtering in network 92, 94. The boosted H.T. voltage derived from source 60 and capacitors 56, 62 may be used to supply H.T. to a further stage, e.g. to the frame scan generator 28 via filter network 98, 100.

Title: Remote-Control Manoeuvring System for a Reversible Internal Combustion Engine
IPC: B63H21/22
Filed: 1967-03-20
Abstract: 1,171,523. Preventing wrong movement of parts of engines. GOTAVERKEN A.B. March 20, 1967 [April 7, 1966], No.12932/67. Heading F1K. [Also in Division G4] In a remote control manoeuvring system for a reversible internal combustion engine e.g. a direct-coupled marine engine, the fuel supply is cut off if the direction of rotation of a shaft in the engine disagrees with that for which the reversing gear is set. A rod-shaped member 5, Fig. 2 provided with a central boss 6 is arranged to slide transversely with respect to shaft 19 which is coupled to the engine, being normally restrained in a central position by means of springs 21. Boss 6 is hollow and provides a housing for a cylindrical member 10 capable of sliding within it and normally held out of engagement with shaft 19 by means of springs 13 which engage a disc-shaped upper portion 11. When air pressure is applied above piston 17 it engages member 10 and forces it into contact with shaft 19; roughened friction surfaces on member 10 and shaft 19 then cause transverse movement of the member 5 to occur in a direction dependent upon the direction of rotation of shaft 19. In accordance with the sense of that movement one or other of the engaging members 22, 23 carried by either end of the member 5 operates the corresponding one of two valves 24, 25. When reversing handle 28, Fig. 1 is moved to either of its extreme positions cam 27 causes one of the forward and reverse valves 29, 30 respectively to open, admitting air from supply line 31 to the corresponding control line 33, 32. The admission of air to either control line causes switch over valve 34 to operate and admit air to cylinder 15 in which piston 17 (Fig.2) operates. Rotation of engine shaft 19 then causes movement of member 5 to occur, whereby one of the valves 24, 25 is operated and couples the corresponding air line 32, 33 to switch-over valve 36, air only reaching the valve however, if the rotation of the shaft is in the appropriate sense. The fuel supply to the engine is normally blocked, but switch-over valve 36 when energized operates a release mechanism 37 unblocking the fuel supply.
